I mean when you adjust the camber or the caster on the front suspension (or on the rear for that matter) you move the centre of the wheel to a different position - thus not all W123s sedans will have a wheel base of exactly 2795 mm - it will be something like 2795 mm +/- say 15 mm for example.

Does anyone know this tolerance?

It's probably a few cm's at most.

The caster calls for probably a 1.5 degree range. I doubt the front wheel moves forward that much.

Some dimension figures are also for Euro spec models with smaller bumpers. US dimensions are longer due to the larger US bumpers.

Yeah I thought so. That's why I put +/- 15mm as an example... there must be a tolerance some where for normal use - in other words for adjustments - and not accident damage.
